Benchrest Tools? (and introduction)

Hi Guys,

Been lurking here for quite a while and finally decided to join. I'm 63 and have been shooting since about 7 years old. Worked for 7 years in a gun shop in Cleveland back in the late 70's (Cleveland Custom Gun Shop), but been a diesel mechanic for 42 years. My love for the shooting sports includes everything from plinking with my pellet rifles to blasting out to 500 yards with my AR10 and M1A. I think the thing I love most though is the reloading aspect of the sport and could spend hours in my reloading room.

Today I came here to ask if anyone could ID a couple of items recently acquired from an older gentleman. I believe these items to be a concentricity gauge and some type of group measuring device. The measuring device also came with what appears to be ink stamps for marking 1½" Bullseyes. I would like to know if my assumptions of these items is correct, if they were commercially made, and what, if any value they have. IMG_20161005_091231187.jpg IMG_20161005_091515828_HDR.jpg
 
No help here! But, the one with the dial looks interesting.

The brass weight on the tip end of the dial indicator is holding down one of the target dots. BTW, the entire unit is made of solid brass, and is mounted on top of a piece of curved steel.
 
I remember seeing something like that in Precision Shooting.

A die was used to cut a disc style target. The shooter than add his favorite aiming spot. The match was one shot closest to center per target.
After the shot, the target was placed on the measuring machine.
The bullet hole was slid over the mandrel and spun. the indicator was set on the edge of the target and read and told how far off center your bullet was.

There was also a bag of cut discs that came with this, some had been stamped with the target dot and some were blank. Thanks for your reply.
